Abstract
A hard disk (530) of a personal computer has a content list file (150) and an encrypted private file (162). A license administration device (520) stores a binding key Kb in a license region (5215B) of a memory. The encrypted private file (162) can be decrypted and encrypted with the binding key Kb stored in the license administration device (520). The license of the obtained and encrypted content data is stored as private information in the encrypted private file (162). Consequently, the encrypted content data and the license distributed by software can be shifted to another data terminal device.
